#2781: The Six Platonic Solids explain

[Six geometrical shapes are shown. All have gray surface areas with different shading to reflect their orientation. There is one shape in the middle with the other five arranged around it roughly in a pentagon. With two at the top, two just below the central and one directly below the central shape. Each shape has a label. The five above the bottom one are names after the platonic solids, and are drawn to look like them. The last one at the bottom has a roughly conical shape with a round base, a triangular tip, and a rectangular extension at the bottom. It surface also seems to have parallel grooves or ribs. Here the labels in reading order with the four rows mentioned above used.]

Cube

Dodecahedron

Icosahedron

Octahedron

Tetrahedron

Jorb

[Caption below the comic:]

Mathematicians long believed there were only five platonic solids, all regular polyhedra, until this year’s discovery of the Jorb.
